Resumo

A redução de custos por meio da melhoria na eficiência energética é um fator determinante para a otimização dos processos operacionais e a sustentabilidade econômica de organizações. Uma forma de se alcançar níveis significativos de eficiência energética é utilizando sistemas de aquecimento, ventilação e ar condicionado, energeticamente eficientes, para novas instalações industriais. As salas limpas, utilizadas em empresas biofarmacêuticas, exigem altas taxas de troca de ar para manter a higienização, o que consome muita energia elétrica. Esse artigo analisou dados coletados de fontes terceirizadas, demonstrando um método usado em uma instalação biofarmacêutica na Irlanda. O objetivo do estudo foi calcular os parâmetros relativos à eficiência energética antes e depois da implementação do controle do volume de ar fresco, visando verificar a eficácia desta abordagem na otimização do consumo de energia e do desempenho da ventilação. O estudo de caso analisou 185 salas limpas de diferentes tamanhos e classificações, observou-se que todas as salas excederam a troca de ar por hora recomendada. Os dados indicaram que salas com volumes mais elevados apresentavam maior desperdício de energia, destacando a importância de otimizar a gestão do fluxo de ar em grandes ambientes de salas limpas. A implementação de controle de volume de ar apresentou uma redução de 8,87% no consumo de energia dos ventiladores, equivalente a uma diminuição de 46.666 unidades de troca de ar por hora, anualmente. Essa diminuição das unidades foi acompanhada por uma redução substancial de desperdício nos ventiladores, totalizando 203.399,1 kWh, economizando mais de €49.055,81 por ano usando estratégias de controle de gradiente de pressão no sistema de ventilação. Em geral, o presente trabalho fornece uma estratégia para melhoria de eficiência energética em indústria biofarmacêutica e destaca os benefícios econômicos e a economia de energia associados à implementação do método proposto. Dessa forma, oferece uma solução prática para reduzir custos operacionais e impacto ambiental, enquanto mantém os padrões de limpeza rigorosos, essenciais para operações em salas limpas.
